The Water Authority of Jordan (WAJ) is restructuring the Amman water network within the framework of a $250 million (U.S.) capital investment program. Dorsch Consult (DC) has been assigned to redesign the congested, most densely populated core of Amman (300,000 population). Time constraints and the pressure to quickly reduce water losses and improve customer service led to extremely short design periods.
Consequently, DC made use of the existing digital network maps prepared under ARC/INFO and combined them with Oracle database systems for customer management, a hydraulic model using PIPE2000 (KYPIPE). ArcView GIS was used as the major working environment not only to graphically present results of hydraulic modeling, but also to completely redesign pipe networks. Updating of the water demand analysis was done by using actual consumer data out of ARC/INFO, automatically assigning demands to network nodes used for the hydraulic modeling.
Applying the above described approach not only shortened the design period by approximately 30 percent, but provided more accurate, transparent, and realistic water network layouts.
